Bought the TPLINK for WLAN expansion (repeater). I already have a router / DSL modem from TPLINK who also WPS extension can, just like these can use this to. Once configured, no more internet is accessible. No device has more Internet. As normal repeater function (without WPS) he can actually expand the WLAN. IPhone and iPad, as well as all other devices have connection (partially halting the Internet radio and video). Time with a router and other times with the. Time is not the Internet and times. I am iMac (2012er) have the most problems. This has connection to one or the other routers in the network, but never! Internet. Only when I turn off the n-standard, then go, but not permanently. Very strange. I have tried all possible settings and announced online. But I do not have it up and running. In Video, cancel the streams. Without repeaters, this was not the case. But the coverage was just very limited. Schade, three weekends vergeigt. Amazon has kindly taken back the device, since it does not serve its intended purpose with me.
